10 Demos which demonstrate the features of the FAT-Engine. The FAT-Engine is a generic raycasting engine for games which may be used by Developers to assemble first-person games (Aventures, RPGs, Shooters etc.) quickly. The engine itself supplies the complete "world-rendering" part including multidirectional sprite and sliding doors support. The rest is up to the "client" program (actually rendering speed: HW2 - 825 frames per minute / HW1 - 660 frames per minute). If you are interested in making your own games based on the FAT-Engine, download the FAT-Engine SDK from the TiCT-HQ at http://tict.ticalc.org (the SDK contains the sourcecode of the Engine and the Demos, too).
